High Performance Message Passing Library for Maestro2 Cluster Network

Keywords

Abstract

A cluster has become a popular platform for high per
formance computing. Currently, many PC clusters are
organized with cost-effective conventional wide-area
network technologies to connect each processing elements.
Here, it is difficult to extract potential performance of the
cluster, since there is the disparity between the wide-area
network technologies and the performance characteristics
required by cluster computing. We have developed a net
work to build high performance PC cluster, called Maes
tro2 cluster network. This paper describes about high per
formance communication library for Maestro2, named
MMP. First, we describe the novel technique, design, and
implementation of Maestro2. Then, we present a design
and an implementation of MMP. We also show experi
mental results to evaluate the basic performance of MMP
and compare it with raw performance of Maestro2. The
experimental results show that MMP can extract maxi
mum performance from Maestro2.
